They are a bit faster, and that, plus the 800MHz FSB will give him a healthy performance increase. engage16, you might also see a slight improvement in game performance, but don't expect much. manjil, the 8500GT is an okay card for older games. Not so much for newer games. It's performance is about equal to a 6600GT/6800 vanilla(regular). It'll play Half Life 2 and Doom 3 maxed out. I'd say anything 2005 and older will be alright on that card.
